Abstract: Abstract of the Invention A data processing system the central processing unit (CPU) of which is responsive to and executes microinstructions generated by the decoding of macro-instructions so as to provide one or more data processing operations.  The sys-tem is arranged so that such microinstructions can be supplied to the CPU from a CPU-resident microcode decoding logic or from one or more external microcode decoding units.  Each of the external units can identify a macroinstruction which it is capable of decoding and includes logic for externally providing one or more microinstructions which result from the decoding process.  If an exter-nal microcode unit and the CPU-resident decode logic are both capable of such decoding operation. the external unit overrides the CPU decoding logic and con-trols the decoding operation externally.  The external microcode unit includes logic for monitoring the number of microinstructions supplied to the CPU which have not yet been executed by the CPU.

Abstract: TIME DRIVEN DISPLAY UPDATING              Abstract of the Invention A data communications system for asynchronous communication having at least two data transmit/receive terminals wherein the display is periodically updated with new send or receive data.  In the receive mode the data is accumulated in a receive buffer for a predetermined time interval and then transferred into a text storage buffer which then activates a display access method to process the stored data and update the display.  The display access method then goes into an "idle" mode and waits for the next transfer of data which does not occur until the predetermined time interval has expired.  In the transmit mode the send data is transmitted without a delay but the display is updated after the predetermined time interval has expired.

Abstract: Apparatus for Shingling Stack of Flat Articles Abstract Apparatus is provided for taking a stack of flat arti-cles such as folded newspapers, and delivering them successively to a conveyor in an overlapped or shingled arrangement to move to a processing station for labeling or addressing or for opening them to receive inserts.  A rectangular hopper or gate is located over a traveling belt means to hold a stack of such flat articles with its converging angle point-ing downstream.  Each bottom article is gripped by the belt means, which is vacuumized in the area under the stack, and is pulled under the gate and downstream.      When a given article is only partially through the gate, the succeeding article is gripped primarily by its side portions and pulled under the gate in overlapping or shingled relation with the preceding one, each article being arranged with its side edges at a substantial angle to the direction of travel.  A shield underlies the rear portion of the stack to prevent gripping the rearmost portions of the articles until they are moving with the speed of the belt to prevent distortion or damage.

The back pack is in the form of an inverted hollow conic section, open at the top only with a pair of spaced flat bars, each parallel to the axis of the conic sec-tion, fixed to each other and to the conic section and located at a spaced distance from the conic section.          Padding is fixed to the exterior of each bar so that it may comfortably rest against the back of the user.  A flexible harness unit is attached to each of two spaced points on each bar and shaped so as to fit about each shoulder and the chest of a user, when the back pack is worn.  The back pack, when rested on the bars in the empty condition on the ground serves itself as the body of a decoy, to which a detachable head unit may be fixed.

Abstract: Abstract of the Disclosure A swivel assembly comprising a base plate, a swivel plate mounted on the base plate for rotation relative thereto, bearing elements between the opposing inner faces of the plates, and a fastener connecting the plates.  The fastener comprises a bolt having a head on the outer face of the base plate, and a threaded shank extending through axially aligned holes in the plates.  The fastener further comprises a nut on the outer face of the swivel plate threaded on the bolt for drawing the swivel plate toward the base plate against the bearing elements.  Both the head of the bolt and the nut are freely rotatable relative to the plates, with the head of the bolt being generally accessible for being turned, and the nut being rendered generally inaccessible by an object mounted on the outer face of the swivel plate.  A lock selectively holds the nut in fixed angular position relative to the swivel plate to ensure relative rotation of the nut and bolt upon turning the head of the bolt, whereby the resistance of the swivel plate to rotation relative to the base plate may be adjusted.

Abstract: ABSTRACT The present invention relates to an improved demodulation system which improves the noise characteristics for the demodulation of a wideband television FM signal.  An adapter for improving the C/N ratio is provided at the output of a bandpass filter, and the output of the adapter is applied to a discriminator which demodulates the FM signal through a limiter.  The adapter is comprised of a variable bandpass filter, the center frequency and the bandwidth of which are controllable, and the variable bandpass filter is inserted in the FM signal path.  The bandwidth of the variable bandpass filter is controlled so that it is wide when the input carrier level is high and is narrow when the input carrier level is low.  The center frequency of the variable bandwidth filter is controlled so that it follows the instantaneous frequency change of the color sub carrier component (3.58 MHz) of the FM signal.  A phase detector is coupled with the input and the output of the variable bandpass filter in order to derive the color sub-carrier component, and the output of the phase detector controls the variable bandpass filter through a narrow-band bandpass filter.  This system is an improvement over the prior art in that it will follow the instantaneous frequency change of the FM input signal to the system, and improve the impulse noise characteristics which reduces the demodulated waveform deformation.

Abstract: Abstract A secondary storage facility employing serial communications between drive (30) and controller (20).  A dedicated cable (10) of four conductors is used to connect each controller/drive pair.  Each conductor carries one undirectional channel.  A first channel (16) is used for command messages and data sent from controller to drive   A second carries response messages and data from drive to controller (14).  Third and fourth channels (18 and 12) carry real-time control signals from controller to drive and from drive to controller, respectively, indicative of controller and drive state, for use in synchronizing and coordinating transmission.          Each of the real-time state signals comrpises a repeating bit pattern of predetermined pattern length; each bit in the pattern has a predetermined meaning.  (Figs. 3, 4) A multi-layered protocol is employed for controller-drive communications over the cable.  The first level governs the electrical transmission of messages.  Framing and data operations occur at a second level.  A third level is used for command and response exchanges.  The protocol is synchronous and supports variable length, multiple word messages, each bounded by specific beginning and end frames.    Specific command/response exchanges are identified.          One is for communicating from the drive to the controller certain parametric information about the drive, which the controller must know to be able to use the drive.          Another enables a host computer to selectively disable and enable the read-time drive state signals, to allow the host computer to determine all paths for accessing each drive with which it can communicate.    Each drive may employ multiple error recovery techniques; the controller signals the drive to try such techniques in sequence, according to descending a priori probability of success.  The controller does not know or need to know the details of the error recovery procedures.
